china wall sealant??

Maybe we could get a discussion started on spark plug gapping? LOL

I thought we had one going. Pinion angles is where I need help. I have it 25 degrees nose up and it’s still not right. One question I’ve always had is I think my spark should be hotter. I don’t want to hurt anything but if I went from black to red spark plug wires would I burn a piston.
